Moderate-sized tree, the branchlets glabrous or nearly so, lenticellate but not prominently so. Leaves moderate, bipinnate, the pinnae l pair, the leaflets 3 to the pinna (terminal pair and outer member of reduced basal pair?); petiole short and condensed, 3-10 mm. long, rugose, callous basally, bearing between insertion of the pinnae a sessile patelliform or subpeltate gland; rachis of pinna usually about 2 cm. long, sulcate and puberulent above, commonly but not always bearing a gland between insertion of terminal pair of leaflets; leaflets narrowly ovate-lanceo- late, lanceolate or elliptic, 4-12 cm. long and 1.5-3.5 cm. wide, cuneate or sub- cuneate basally, usually bluntly acute or acuminate apically, glabrous on both sides, inconspicuously reticulate; stipules lanceolate, about 2 mm. long. Inflores- cence lateral on older wood, of short, lax, fasciculate spikes; spikes about 2 cm. long, scarcely pedunculate, subglabrous; bracts lanceolate, about 1 mm. long, sub- persistent. Flowers small, sessile, whitish or pinkish, fragrant; calyx cupular, about 1 mm. long, glabrous except the minute teeth puberulent or ciliate; corolla tubular- funnelform, 6-7 mm. long, glabrous; stamens many, about 16 mm. long, the staminal tube well exserted; ovary pubescent.

Note
|
The species in Panama seems to exhibit stability unexpected in the genus. Similar to P. latifolium and other species, the differences, although minor, appear surprisingly constant.
